Thanks for any help you offer. My 2000 Buick LeSabre's cruise control won't engage. The LED next to the on/off switch lights up when I turn it on. The "CRUISE" light in the dash lights up when I set the speed. The only part that seems to not work is the speed actually being set. The car begins slowing down as soon as I take my foot off the gas. I checked the cruise fuse and it's fine. Why isn't the cruise engaging?

There are a couple of things that will disable cruise, first is brake switch, or parking brake switch.

Next would be the gear selector.

Also the car would need to be in closed loop, that is the engine must be at temp. If thermostat is bad, it will not heat up and cruise will not work.

Even thought you see no powertrain codes you may have a body, or chassis code. These can be read by trusted garage.
